1-Channel Duplex RS-485 Fiber Optic Data Modem

System Design

Fiber Optic Data ModemVOS-1FOM-D485T/R provides for the digital transmission of 1 Channel duplex RS-485 data (2-wire or 4-wire). Rs485 to fiber converter, typical applications for Pan/Tilt/Zoom for Surveillance Systems, Data Control for Manufacturing / Assembly Platforms, Data Control for Traffic Monitoring / Control / Analysis...etc.Stand-alone or rack-mount. All units of VOS-1FOM-D485T/R come in an insert card version.The cards can be inserted into our 14-slot, 19inch 2U or 4U rack-mountable card cage (VOS-CH02 or VOS-CH04). Single-Mode or Multi-Mode, VOS-1FOM-D485T/R only can support FC/PC or ST/PC connector, can be used in Daisy-Chain system (Need to customize) The Transmission distance range according to the Optical Budget.Manufacturer's standard is: Single-mode 20km.

Note:
• The Optical Power Budget data fit Mulit-mode(62.5/125 μm),Single-Mode(9/125 μm).
• When using 50/125 μm multimode fiber, subtract 3 dB from the optical power budget.
• Optical transmission distance is limited to optical loss of the fiber and any additional loss introduced by connectors, splices and patch panels.
• Maximum transmission distance is also limited by fiber bandwidth.
• Power adapter is manufactured by third party and is supplied with fitted screw-terminal output cables.Power adapter included (for standalone) US, European, UK or Australian power plug.
• Please feel free to consult factory for any special requirement and customization.
